If you like chamber music, Get.This.Boxset.Now. It is a gem. The Heifetz-Piatigorsky concerts let us experience the concerts that violinist Jascha Heifetz and cellist Gregor Piatigorsky held starting in, when both music giants were in semi-retirement from the concert stage and wanted to continue performing music in small settings for their friends. The concerts came to an end in 1974 when Heifetz injured his shoulder. (Piatigorsky died 2 years later.) They are occasionally joined by musicians such as Artur Rubinstein at the piano and William Primrose at the viola. The boxset is a box of 21 CDs all individually encased in cardboard sleeves reproducing the exquisite original artwork, with an informative color booklet providing a short essay and a detailed description of the contents of each CD. I found the sound to be of excellent quality. Overall, an excellent purchase. At $56 on Amazon, this is absolutely a bargain for chamber music lovers.
Below is a detailed description of the CDs' content, since I didn't readily find one online.
